MANURE-SPREADER.

. b all 'urhom it may concern:

Be it known that I, Dacron K. VVILsoN, a citizen of the United States of America, and a resident of W'aterlm'). lllackhawk county, io'wa. have invented certain new and useful lmprm'ements in Manure Spreaders, of which the following is a specification.

M y invention relates to improvements in manure spreader-s, and the objects of my improveinents are these: first, to provide an 93 2 is a. detail view of the spacing-means between said wagon-box and its bolsters; Fig. 2% is an upper plan View of the driving-pawlcarrying lever; Fig. at is a side elevation of a manure spreader wagon box equipped with a slightly n'iodified form of in improved adjustable pawl-and ratchet drivingmechanism for the conveyer-apron. Fig. 5 is an upper plan view of the pulling-pawl 42 shown in Fig. 4, and Fig. (i is an elevation of the comb-frame with its Widelyspaeed supports.

Similar numbers refer, to similar parts throughout the several views.

The wagon-box 29 contains a movable conveyerapron 30, and has at its open deliveryend a distributingdrum l secured to a transverse shaft 2 whose ends are rotatably mounted in hearings in brackets 23 fixed to said box. The conveyer-apron 30 is actuated by a transverse shaft 25, having a ratchet-wheel secured on its right-hand end. A emu-wheel 3 is secured to the right-hand end of the shaft 2. A lever (i is medially pivoted on a stud 7 extending from the bracket This lever, shown in plan in Fig. 3, is bifurcated at each side of its pivotal mounting, an anti-friction roller 4 being mounted in the rear bifurcation on pintles 5, and adapted to operatively contact with the working edge of the ca1nwheel 3. The up Specification of Letters Patent.

Serial No. 448,549.

per end of the driving-pawl 22 is mounted in the forward bifurcation of said lever on pintles 9, and its lower end is adapted to operatively contact with the teeth of the ratchet-wheel 24. Pivotally mounted on a stud 18 also extending from the bracket 23, is a lever having peculiarly-curved members 10 and 13, which however are directed substantially at right angles to each other, the member 10 extending backward into the path of travel of the forward member of the lever (3, while the member 13 has an orifice extending through its upper end from front. to rear to receive slidablv therethrough the rear portion of the rod A split-key 15 secured to the rod 27 a short distance anterior to the lllEll'llJEl '13, and a slide 16 having its upwardly directed members slidable on said rod incloses not only said split-key but also a coiled tension spring 14 between one of its members and said split-key. The forward end of the rod 27 is swiveled at to a hand-lever the lower end of the latter being pivoted on a stud 3T projecting from the plate 36 secured to the side of the wagon-box 29. The handlever rocks in a rack-bar 32, which is secured by bolts 31 and 3st to the side 29, and may be secured by engaging means inserted into the holes 41. Vhen the handlever 33 is shifted back, it cai'ises a rearward movement of the rod 27. The slide 16 is thus caused to resiliently contact with the upper member 13, through the medium of the inclosed split-key 15 and spring ll, and induce the member 10 to move a determined distance into the path of movement of the lever 6. The resilient connection prevents any jar or breakage of said parts when the lever is quickly shifted, as the spring gives enough to make the adjustment sufliciently gradual. According as the member 10 is pushed a greater or less distance into the path of movement of the lever 6, the driving-pawl 22 will click back over a different number of teeth of the ratchet-Wheel 2st, and thus the speed of movement of the apron 30 may be enhanced or retarded.

The numeral 8 designates a boss on the upper end of the pawl 22 above its pivot which is adapted to contact with the member 10 operatively in the adjustment above described.

I have shown herein two holding-pawls, 20 and 21, located as shown with 20 in adti U vance of 21 but the pawl 20 being hung with reference to the pawl 21 so that when one of them has its point at. the root of the ratchctdecth, the point of the other is located about one-half of the length of a tooth away from the root. of the contacting teeth. This arrangement results in one or the other holding-pawls being in close contact with the ratchet-wheel constantly. l have shown a device for holding both the drivingand holding-pawls resiliently down so as to always he in contact with said. ratchet-wheel and click back thereover. The rear holding pawl Ql is pivoted on the stud l8 and has a forwardly-directed member +9. the latter having a pivotal connection ith the hold-- ing-pawl 20. such connection being the tulcrinn of the latter. The holding-pawl. 20 has a rearwardly-directed projection 44 with a connection 17 to the forward end of a. coiled spring 12. the rear end of the latter having a connection It with the driving pawl 22 at a point a little below its pivot. 9. This spring 12 being obliquely-directed in the line of throw of the said drivingpawl tends to keep it in contact with the ratchet-wheel to click back thereover. while it also d -aws upwardly a little upon the forward member of the lever (B. keeping the latter balanced. also keeping the roller 4 in contact with the can'i-wheel 1;). The spring also keeps both of the holding-pawls in contact with said ratchet-wheel to click back thereover. but varying their contact therewith as above described by reason of the movement imparted by the pawl 522. As the driving-pawl 2') is pushed down. the spring 12 draws upon and moves the member it of the pawl 20 rearwardly pushing the point of the latter into t'ull engagement with the periphery of said ratchet-wheel. The member 49 of the pawl 21. is thereby lifted by reason of its connection with the pawl lit). and thus the point of the pawl 21 is pushed down upon the periphery of said ratchet wheel. Since from the method of mounting the said holding-pawls are alternately onehalt' the length, of a tooth ahead of each other. one or the other of them is always sure to be in practical holding engagement with the teeth of the ratchet-wheel. Since ratchet-wheels formed of malleable iron are often somewhat distorted from the form of a perfect circle in their circumferential teeth. becoming slightly elliptical in form. this arrangement of two holding-pawls as described insures of one or the other engaging the root of teeth on said wheel.

I have adopted spacing-means for the wagon-box 2%), whereby such box may be detachably connected to bolsters ot' tjliflerent. running-gear in succession. The spacing device consists of a. hanger 26 secured to each side of the box underneath. such hangers having brackets 28 on their inner sides secured by bolts or other means. The upper surfaces 38 of said brackets are curved downwardly, and are adapted to be used as slideways for the ends of the conveyenapron and. supports therefor. The lower part of each bracket is formed with downwardlyprojecting lugs 39 and 40. having tlujirehetween a socket 47 or rectangular torm but open at the bottom to fit over a bolst er is removably. The same spacing device may be used tor one or both axles and their bolsters. and enables the user to quickly remove or change the box from one set of running gears to the other when desired. as well as to adapt the mechanism of the spreader tor use with such gears where different vertical adjustment can be had and is necessary by using bolsters of different heights.

The device shown in Figs. 4 and 5 is substantially the same in its driving-mechanism for the convcyer-apron as that shown in the other figures. A variation is made. however. in the lever U. in that it has a stud instead of the driving-pawl to contact with the member 10. The driving-pawl 42 is formed to be a pulling instead of a pushing pawl. by directing it forward. and having its point -13 directed backward. The pawl 42 is longitudinally slotted to permit the holding-pawls 2t) and 21 to work through it. while the rear end ofthe spring 12 is connected tothc projection 45 thereof above the pivot 2!. so as to keep said pawl in contact with. the ratchetwheel.

The comb SW 5?) whose pintles 52 are pivoted in the ends of supports 50. overhangs the drum 1. and has a spring connection in) at each end. from lugs 5! to the points lit. The supports are spread outwardly from the tops of the sides 29. to prevent any clog ging ot' overhanging parts of the load in passing by them. as shown in Fig. c.
